Electronic control of a novel system for lifting large structures

摘要

This paper presents a novel system that allows elevating large structures by using a set of lifting towers that, adequately controlled with a synchronized operation, succeed in pulling the spatial mesh up to the height where it should stay. By doing so, the mounting of the spatial mesh can be carried out on ground in an easier and, most important of all, safer way; it also gives rise to a shorter final time -and, thereby, a cost reduction. This paper deals with the mechanical structures designed to pull the mesh up, and focuses on the electronic system that allows controlling their movement. Comments about the overall control that coordinates the operation of all of the mechanical structures involved are also provided.
